Letters Patent No. 73,634, clated January 21, 1868.

MPROVEMENT IN STEAM-GENERATORS..

TO WHOM vT MAY CONCERN:

Be it known that I, AGUSTUS W. NEWELL, of Bradford, MeKean county, in the State of Pennsylvania.,v

have invented a. new and useful Improvement in Adjustable Fire-Bones for Boilers; and do hereby declare that the following is a full clear, and exact description thereof, reference hein,r had to the aeoompanying drawings, and to the letters of reference marked thereon, and making a part of this specification, in which my invention is shown as attached to a cylinder boiler.

The object I have in view in this invc-ntion is so to coustruct a fire-box, to be used with cylinder, locomotive, or other kind of boilers, that it may readily be attached or (letached, as oceasion may require. To do this, I make a fire-box in any required form, with or without water-space, as mzxy be desired, or with a partiai waterspace. It may be made to extend a part or the whole length of the boiler, and the steam and water of the firebox and boiler are connected by means of pipcs with expansion joints. The fire-box is built entirely separate and independen-t of the boiler, and of different sizes and forms necessary to fit the different sizes and varieties of boilers. v

Having thus described the manufucture of my invention, I will now name the various parts, as shown in the dra-wings.

A is the adju stable fire-box. B is a cylinder boiler. C O are lugs upon the fire box and boiler, through which the bolts are passed to hold the two together. D is a steam'pipe with, E, expansion-joints to 'connect the steam iu the boiler and fire-box. F are pipes, shown in red lines, to connect the waterlin the fire-hox and boiler. 4

`In the use of my fire-box, made as above cleseribed, there will be n. great saving effeoted in transportation, and much trouble avoicled in the handling and setting., At any time repair-'s are necessary, it may be removed and another substituted, thus saving` a great loss of time, especially when used upon .looomotive-boilers. The combustion of fuel used will also be inereused by direction of the draught from the rear of the fire-:ox to the front end of the fiues, as shown in fig. 2, the arrow indicating the direction of the draught.

Figure 1 is a perspective view of my invention.

Figure 2 is a Vertical seetional view of the same.

The same letters indicate like parts in each figure.

What I claim as my invention, and desiro to secure by Letters Patent, is-v The construction of an adjustuble fire-box, as hereinbefore desc'ribed, provided with suitable fastenings C G, steam-pipes D, with expansion-joints E and proper water-pipes F, arranged substantially as and for the purposes described.

AUG. W. NEWELL.
